===> it *is* a bug in R after all :

address 0x7fff423ab000, cause 'memory not mapped'
and yes, the bug is device dependent:
E.g., it nicely works for postscript() or pdf()
> postscript(); plot(1); axis(1, lty=NULL) ; dev.off()
null device
1
and it's ok for type = "Xlib", but not for the default
type = "cairo":
> x11(type="Xlib")
> plot(1); axis(1, lty=NULL)
> x11(type="cairo")
> plot(1); axis(1, lty=NULL)
